Thanks, might be related to linux versions of the browsers. Nope, tried the hard reload. No errors in console, just this warning: The resource https://cdn.auth0.com/styleguide/core/2.0.1/fonts/fakt/FaktPro-Normal.woff2 was preloaded using link preload but not used within a few seconds from the window's load event. Please make sure it wasn't preloaded for nothing. Nothing seems to happen when I drag and drop to re.order. no requests are sent.
